[Bluej-discuss] Extension API clarification: Compile Event

[Michael Kölling]

In addition to Josh's point: The fact that separate compile events are  
generated during standard compilation is the current implementation  
behaviour, but we make no guarantees that it will remain so.

The implementation has changed in the past, and may change in the  
future, so you should not assume that it is always only one. The  
framework is free to produce a single event with a list, or multiple  
events, and your extension should be able to process both.

Regarding the COMPILE_FAILED_EVENT: I believe that this is correct  
(but maybe Ian can comment - he knows this better than I do).
